JOU RNAL-BOX FOR SH EAVE-WH EELS.

SPCIFICATION forming part of Letters Patent No. 415,791, dated November 26, 1889'.

Application filed March 8, 1889. Serial No. 302,503. (No model.)

.To all whom it may concern:

Be it known. that I, WILLIAM PHENIX, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvement in Journal-Boxes for Sheave- Vheels, of which the following is a full, clear,

and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in the class of journal boxes or bearings that are more especially intended for use on sheave- Wheels in the cable traction system.

The object of this invention is to provide the sheave-Wheel bearing with a continuous and uniform lubrication. p

Figure l is a vertical central section in plane l, Fig. 4, looking in the direction indieatedlby the arrows; Fig. 2, a side elevation; Fig. 3, a side elevation of the journal or bearing block and sheave-axle shaft removed from the journal-box; and Fig. 4, a horizontal section in plane 4, Fig. I, looking in the direction indicated by the arrows.- n l Referring to the drawings, A represents the bed-plate; B, the journal-box; C, the axle or shaft, and D the bearing-block. Thejournalbox is provided with the oil-chamber a, partially filled with oil, as shown in Fig. I. The solid bearing-block D is of Wood, bass-wood being preferred on account of its soft porous nature and qualities for readily absorbing and conducting the oilto the bearing. Any other Wood possessing these characteristics may be substituted for bass-wood. The sides a a2 of the journal-box are provided with vertical rectangular recesses a3 a4, into which the bearing-block D fits, as shown in Fig. 4. The wood block is set vertically in the oilchamber and rests on the bottom, the lower half being submerged in the lubricating substance, as shown in Fig. 1. The lower end of the block is cut away at right angles to form grooves or chambers b b and provides the feet b2, thus increasing the oil-absorbing surface. The bearing-block is made to fit the recesses a3 a4 in the side walls very closely, so that the same is iirmly secured in a iixed immovable position. The oil absorbed by the wood Will be conducted to the journalbearing, thereby affording a constant lubrication. When the bearing in the wood block becomes too much worn, it can be conveniently replaced, the cost being comparatively nothing. The cap E is hinged at one side and is provided with downwardly-projecting flanges d, overlapping the sides of the box, and thus excluding the dust and dirt.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with a journal-box having an oil-chamber and provided with recesses in the solid Walls, of a wood bearingblock arranged vertically in said chamber and having the lower end resting on the bottom of the oil-chamber, provided with grooves or channels, as described, and the axle or shaft having a bearing in said block, substantially as and for the purpose set forth.

2. In a self-oilin g bearing for sheave-wheels, the combination, with a journal-box having an oil-chamber and provided With recesses in the side walls, of a woodbearing-block engaging with said recesses and having the lower part submerged in the lubricant, the axle or shaft inserted in said block, and the cap E, provided with downwardly-proj ecting Ilan ges cl, substantially as and for the purpose set forth.

VILLIAM PHENIX.
